TELESCOPE RIFLE SIGHT.

Application filed January 18, 1922. Serial No. 530,060.

To all whom it may concern:

Be it known that, I, WARREN S. BELDING, a citizen of the United States,and a resident in the borough of Philipsburg, county of Center, andState of Pennsylvania, have 1nvented certain new and useful Improvementsin Telescope Rifle Sights, of which the following is a specification,reference being had to the accompanying drawings.

This invention is especially designed for use in conjunction with theUnited States Army rifle, model 1903, which is now the standard militaryrifle of this country. Among other advantages this invention obviatesthe use of screws, renders unnecessary much drilling, tapping orsoldering now required, may be instantly applied toor removed from thearm and when applied 10- cates and adjusts itself so accurately thatresighting is not necessary.

In the accompanying drawings, Fig. 1 is an elevation of the breechsection of a rifle showing my invention in position thereon;

Fig. 2 is a vertical sectional view on the line 2-2 of Figure 1;

Fig. 3 is an elevation of what I call the mount base bar;

Fig. 4 is a plan view of the base bar shown in Figure 3;

Fig. 5 is a plan view of the rear sight band which forms a permanent;and usually integral part of the barrel as now made;

Fig. 6 is a vertical sectional View taken on the line 66 of Figure 1.

In the drawing 1 represents the stock, 2- the barrel, 3 therear sightband as now made, 4- the cartridge manipulating devices, 5 the cartridgereceiver. All of these parts are or may be the same as now made and uponthe removal of the present telescope and its coacting parts from therifle the parts above enumerated will remain permanently and rigidlyattached thereto.

6- represents my mount base bar, which is a rigid, inflexible metallicpart having at its front and rear ends a dovetailed part 7-7 providedwith stops 8-8 adapted to coact with the telescope holders 99 all asfully illustrated and described in my pending application for patent forrifle sights Serial Number 510,345, filed October 25, 1921. The base barhas also at about its medial part a horizontally bored hole 10 adaptedto receive a bolt or pin 11 which, passing through the lugs 1212 formedon a plate 13, pivots the base bar to it. The

plate 13 is provided with a suitable counter bore 15 adapted to snuglyreceive the boss 14 on the sight band, so that the ends of the platewill, when it is swung into paralellisrn with the barrel, pass beneaththe flanges 16 16 at the ends of the band 3.

The base bar has also a vertically bored hole 17 through which passes athumb screw 18 which is threaded into the plate 13 and is provided witha. thumb nut at its upper end. On the rear end of the base bar there isformed an inverted V-shaped block 19, which is adapted to rest on thetop of the forward part of the receiver 5 (see Figures 1 and 2). 202Oare two lugs formed on the plate 13 for the more secure support of thebase bar.

The operation is as follows: The telescope and its coacting parts as nowmade, having been removed my new base bar is pivoted to the plate 13 bythe bolt or pin 11 as described. The base bar and the plate are thenadjusted upon the permanent rear sight band 3, as also described, thethreaded thumb next 18 being now turned inwardly the result will be thatthe plate 13 will be drawn snugly against the flanges 16-16 the V-shaped block 19 pressed forcibly down upon the top of the receiver 5,and all lost motion in either the pin 11,the thumb screw or in any otherpart taken up, thus effecting a very rigid and satisfactory mount forthe telescope, and it will be especially noted that all these contactsare eflected by positive screw action, not by reliance on the resistancyof springs as in certain earlier constructions which have provenunsatisfactory. Finally, much machine work and all resighting iseliminated.

If desired the base bar may be extended so that the V-shaped block willrest upon the rear instead of the forward part of the receiver. Thisconstruction, however, will not ordinarily be desirable since itinterferes with the clip cartridge method of loading.

It will be obvious to those who are familiar with such matters thatchanges may be made in the detail of construction without departing fromthe essentials of my invention. I therefore do not limit myself to suchdetails.

I claim 1. In a telescope rifle sight the combination of a base bar, aplate, a rear sight band, and telescope holders, the base bar beingpivoted to the plate and the plate adapted to interlocking engagementwith the rear sight 10 tion of a base bar, a plate, a rear sight bandand telescope holders, the base bar being pivoted to the plate and saidplate adapted to interlocking engagement with the rear sight band, meanson the base bar to support the telescope holders, means on the undersideof the base bar to support its rear end and a thumb screw which passesthrough the bar and is threaded into said, plate.
